Magnetic traction device for impacted tooth

Abstract

A magnetic traction device for impacted tooth, comprising a first magnetic component fixed to a normal tooth and a second magnetic component fixed to an impacted tooth. There is an attractive magnetic force between the first and second magnetic components, thereby pulling the impacted tooth toward the direction of the normal tooth where the first magnetic component is located.

1 . An impacted tooth magnetic traction device, comprising:
 a first magnetic component fixed to a normal tooth;   a second magnetic component fixed to an impacted tooth without a crown, wherein there is an attractive magnetic force between the first and second magnetic components, thereby pulling the impacted tooth toward the direction of the normal tooth where the first magnetic component is fixed; wherein, the impacted tooth has two opposite side walls and a first side hole on one of the side walls, the first side hole communicates with a pulp chamber of the impacted tooth, and the second magnetic component passes through the first side hole and the pulp chamber to lean against the other side wall.   
     
     
         2 . The impacted tooth magnetic traction device as recited in  claim 1 , wherein the first magnetic component comprises a casing, a magnet or iron block housed within the casing, and a cover that seals the casing, with the cover being fixedly attached to the normal tooth. 
     
     
         3 . The impacted tooth magnetic traction device as recited in  claim 2 , wherein the cover is adhered to the normal tooth. 
     
     
         4 . The impacted tooth magnetic traction device as recited in  claim 1 , wherein the second magnetic component is a magnet or iron block. 
     
     
         5 . The impacted tooth magnetic traction device as recited in  claim 1 , wherein the impacted tooth has a groove on the other side wall, and the second magnetic component passes through the first side hole and the pulp chamber into the groove. 
     
     
         6 . The impacted tooth magnetic traction device as recited in  claim 1 , wherein the impacted tooth has a second side hole on the other side wall, and the second magnetic component passes through the first side hole, the pulp chamber and the second side hole.
